Several areas of the world suffer a notably high incidence of Shiga toxin-producing . To assess the impact of persistent cross-species transmission systems on the epidemiology of O157:H7 in Alberta, Canada, we sequenced and assembled O157:H7 isolates originating from collocated cattle and human populations, 2007-2015. We constructed a timed phylogeny using BEAST2 using a structured coalescent model.

Bots in white coats: are large language models the future of patient education? a multi-center cross-sectional analysis.

Objectives: Every year, around 300 million surgeries are conducted worldwide, with an estimated 4.2 million deaths occurring within 30 days after surgery. Adequate patient education is crucial, but often falls short due to the stress patients experience before surgery.

Angioimmunoblastic T-cell lymphoma: Characterization of clonal T and B cells and a patient-derived xenograft study of coexisting T- and B-cell proliferation.

Introduction: Angioimmunoblastic T-cell lymphoma (AITL) is a rare and aggressive lymphoma with a poor prognosis. AITL is associated with Epstein-Barr virus (EBV)-positive B cells in most cases, suggesting a possible role for the virus in the pathobiology of AITL. Cell lines from AITL patients do not exist and models of human AITL are needed.

Clustering Sequence Data with Mixture Markov Chains with Covariates Using Multiple Simplex Constrained Optimization Routine (MSiCOR).

Mixture Markov Model (MMM) is a widely used tool to cluster sequences of events coming from a finite state-space. However, the MMM likelihood being multi-modal, the challenge remains in its maximization. Although Expectation-Maximization (EM) algorithm remains one of the most popular ways to estimate the MMM parameters, however, convergence of EM algorithm is not always guaranteed.

Transforming the tradition of discrete milk yield correction factors: A continuous 1-step DeLorenzo-Wiggans method.

Over the past decades, various methods have been proposed to estimate daily milk yields from partial yields. Many of these methods divide milking interval time into varied classes, assuming that the yield correction factors are constant within classes but vary between classes. The DeLorenzo and Wiggans (D-W) method has been widely used in the United States, typically following a 2-step process.

Maternal History of Child Maltreatment Predicts Dysregulated Offspring Stress Response System Functioning.

Identifying proximal and multigenerational distal risk mechanisms through which adversity exposure may shape neuroendocrine dysregulation among children is critical to advancing effective preventive interventions for adversity-exposed individuals. Utilizing longitudinal data ( = 247), the current study examined maternal and offspring history of childhood maltreatment (CM) as predictors of offspring cortisol/DHEA ratios, and, in exploratory analyses, extended this longitudinally to offspring depressive symptoms in young adulthood. Youth (ages 8-13 years) initially attended a research camp, then were followed up approximately eight years later (ages 18-22 years).

These compounds were characterized using NMR (HNMR,C NMR, 2D NMR), IR, HRMS and UV-VIS.

Correcting scale distortion in RNA sequencing data.

RNA sequencing (RNA-seq) is the conventional genome-scale approach used to capture the expression levels of all detectable genes in a biological sample. This is now regularly used for population-based studies designed to identify genetic determinants of various diseases. Naturally, the accuracy of these tests should be verified and improved if possible.

Sleeve Gastrectomy Versus Semaglutide for Weight Loss in a Severely Obese Minority Cohort: A Propensity-Matched Study.

Background: The rising obesity rates in the USA have led to a surge in various weight loss treatments. Glucagon-like peptide-1 (GLP-1) analogues have shown promise in reducing weight but primarily studied in Caucasian populations. Sleeve gastrectomy (SG) has already proven successful weight loss outcomes.

Anxiety moderates the association between severity of food insecurity and sleep duration among young adults in food-insecure households.

This study examined associations between food insecurity (FI) severity, anxiety symptoms, and sleep duration among young adults in food-insecure households. We hypothesized that more severe FI and higher anxiety would independently predict shorter sleep duration, and that anxiety would amplify the FI-sleep duration relationship. Analysis was conducted on a subsample (n = 96) of the EAT 2010-2018 young adult cohort.

Associations between common genetic variants and income provide insights about the socio-economic health gradient.

We conducted a genome-wide association study on income among individuals of European descent (N = 668,288) to investigate the relationship between socio-economic status and health disparities. We identified 162 genomic loci associated with a common genetic factor underlying various income measures, all with small effect sizes (the Income Factor). Our polygenic index captures 1-5% of income variance, with only one fourth due to direct genetic effects.

Guided Self-Help vs Group Treatment for Children With Obesity: A Randomized Clinical Trial.

Background And Objectives: Family-based behavioral treatment (FBT) for children with obesity is provided in weekly parent and child groups over 6 months. A guided self-help FBT program (gshFBT) is provided to the dyad in short meetings. Both interventions provide the same content; however, gshFBT provides this content in less time (FBT = 23 hours, gshFBT = 5.

Revising the coal mining CH emission factor based on multiple inventories and atmospheric inversion approach at one of the world's largest coal production areas: Shanxi province, China.

Methane (CH) emissions from the coal industry represent a substantial portion of anthropogenic CH emissions from energy-related activities. China ranks as the world's largest coal producer, where Shanxi Province is one of its major coal production regions and accounts for 20.7 % of the national total coal production.

The long-term effects of housing insecurity in young adulthood on subsequent material hardship, physiological and mental health.

Economic and material hardship, including housing insecurity - limited or uncertain availability or access to safe, quality, and affordable housing - is strongly linked to negative physical and mental health outcomes among adolescents and adults. However, data limitations and the inherent selectivity of housing insecurity have hindered comprehensive analysis of its long-term effects on physiological and mental health. This study uses data from The National Longitudinal Study of Adolescent to Adult Health (Add Health) to construct a sample of participants who experienced housing insecurity between the ages of 18-26 (Wave III) to a suitable control group using propensity score matching.

The effect of conflicting versus consistent messaging on older women's support for breast cancer screening cessation.

Objective: Breast cancer over-screening is common in older women. Messaging about breast cancer screening cessation may reduce over-screening but the broader informational environment often emphasizes screening continuation. We aimed to examine the effect of receiving consistent messages about breast cancer screening cessation versus conflicting messages (i.

Designer Organs: Ethical Genetic Modifications in the Era of Machine Perfusion.

Gene therapy is a rapidly developing field, finally yielding clinical benefits. Genetic engineering of organs for transplantation may soon be an option, thanks to convergence with another breakthrough technology, ex vivo machine perfusion (EVMP). EVMP allows access to the functioning organ for genetic manipulation prior to transplant.

Corticosteroids in severe alcohol-associated hepatitis? Not so fast: A systematic review of randomized controlled trials.

Background: Severe alcohol-associated hepatitis (AH) is rising in incidence with a high mortality burden. While corticosteroids are recommended for eligible patients with severe AH, no guidance exists for the timing of steroid initiation, tapering regimens, and surveillance of adverse events.

Objective: We aim to systematically review these variables and provide evidence-based recommendations for the inpatient and outpatient management of severe AH.

Pre-pandemic leukocyte count is associated with severity of post-acute sequelae of SARS-CoV-2 infection among older women in the Women's Health Initiative.

Objective: Although dysregulated inflammation has been postulated as a biological mechanism associated with post-acute sequelae of severe acute respiratory coronavirus 2 (SARS-CoV-2) infection (PASC) and shown to be a correlate and an outcome of PASC, it is unclear whether inflammatory markers can prospectively predict PASC risk. We examined the association of leukocyte count and high-sensitivity C-reactive protein (hsCRP) concentrations, measured ~25 years prior to the coronavirus disease 2019 (COVID-19) pandemic, with PASC, PASC severity, and PASC-associated cognitive outcomes at follow-up among postmenopausal women.

Methods: Using biomarker data from blood specimens collected during pre-pandemic enrollment (1993-1998) and data on 1,237 Women's Health Initiative participants who completed a COVID-19 survey between June 2021 and February 2022, we constructed multivariable regression models that controlled for pertinent characteristics.

Expression Patterns of DLL3 Across Neuroendocrine and Non-Neuroendocrine Neoplasms Reveal Broad Opportunities for Therapeutic Targeting.

Neuroendocrine neoplasms (NENs) encompass a diverse set of malignancies with limited precision therapy options. Recently, therapies targeting DLL3 have shown clinical efficacy in aggressive NENs, including small cell lung cancers and neuroendocrine prostate cancers. Given the continued development and expansion of DLL3-targeted therapies, we sought to characterize the expression of DLL3 and identify its clinical and molecular correlates across diverse neuroendocrine and non-neuroendocrine cancers.

A comprehensive assessment of membrane bioreactor contaminant removal efficacy through analytical chemistry, fish exposures, and microbiome characterization.

Treated municipal wastewater effluent is an important pathway for Contaminants of Emerging Concern (CEC) to enter aquatic ecosystems. As the aging wastewater infrastructure in many industrialized countries requires upgrades or replacement, assessing new treatment technologies in the context of CEC effects may provide additional support for science-based resource management. Here, we used three lines of evidence, analytical chemistry, fish exposure experiments, and fish and water microbiome analysis, to assess the effectiveness of membrane bioreactor treatment (MBR) to replace traditional activated sludge treatment.

Duodenogastric Reflux in Health and Disease: Insights from a Computational Fluid Dynamics Model of the Stomach.

The stomach is responsible for physically and chemically processing the ingested meal before controlled emptying into the duodenum through the pyloric sphincter. An incompetent pylorus allows reflux from the duodenum back into the stomach, and if the amount of reflux is large enough, it could alter the low pH environment of the stomach and erode the mucosal lining of the lumen. In some cases, the regurgitated contents can also reach the esophagus leading to additional complications.
